Someone who isn't a neckbeard who programs? Someone who wears good clothes? Someone who keeps fit?
All of those types of people have been around and programming for a long, long time. There were lots of "typical nerdy programmers" too, and guess what: there still are.
I think it might be useful to explain the central thesis of your book.
At the moment it seems to be written around a marketing strategy: make programmers mad, tell them to download the book while it is free, and hope it makes it towards the top of the Amazon best seller list when you start charging.
Good luck with that. Bro.
Really? There is no indication of that message on the landing page.
"A new crowd of jock-like developers has arrived, more likely to spend the wee hours of the morning at the club than writing code, turning workplaces toxic to others and dumbing down the world of computer science."
Not sure how "turning workplaces toxic" in the opening paragraph translates to "diversity results in better software".
Strange to me you'd come off thinking this. The premise of the book is that diversity and a better portrait of society as a whole (including everybody) in the making will result in better software.
I'd love for you to read it and see, it's free for the next two days on Amazon if you can spare a couple hours. There are a few HN cameos.
